GAS-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 622,224, dated April 4, 1899.

Application filed. March 17,1898.

To all whom it may concern:

Be it known that I, CHARLES H. HATFIELD,

a citizen of the United States of America, and

a resident of Des Moines, Polk county, Iowa, have invented certain new and useful Improvements in Gas-Fixtures, of which the following is a specification.

The object of the invention hereinafter described is to provide improved means for generating gas or vapor from gasol'ene and so burning the same as to produce a white and brilliant light or illumination of high candlepower in proportion to the quantity of oil cousumed.

The invention consists in the construction, arrangement, and combination of elements hereinafter set forth,pointed out in my claims, and illustrated by the accompanying drawings, in which Figure'l is an elevation of the complete device. Fig. 2 is a perspective of the burnerframe detached from the device and from the mantle and chimney. Fig. 3 is a sectional detail view of one of the Ts employed in the device. Fig. 4 is a sectional detail view of a portion of the generating-tube. Fig. 5 is a cross-section of the generating-tube.

In the construction of the device as shown the numeral designates a hanger formed with a hook 11 on its upper end, whereby said hanger may be suspended from a ceiling eye, hook, or other supporting device. (Not shown.) An oil tank or reservoir 12 is mounted by its top on and depends from the lower end of the hanger 10. The reservoir is provided with an ingress-port in its top, closed by a screw-cap 13, and a gage-indicating rod 14 is mounted in the reservoir, projects through the top thereof, and is provided with a float on the lower end carried by the oil in the reservoir in a common manner. A supply-pipe 15 is tapped at its upper end, in. the lower end of the reservoir 12, and the lower end of the supply-pipe is tapped into the upper arm or port of a cross 16. Generators 17 18 are tapped at their inner ends in the lateral arms or ports of the cross 16 and extend horizontally in opposite directions therefrom. The generators 17 18 are provided with stop- 50 cocks 19 20 adjacent to the cross 16, and horizontal coils 21 22 are formed in the central Serial No. 674,279. (No model.)

portions of the pipes of said generators. The generators 17 18 terminate in couplings 23 24, screw-seated on the ends of the pipes thereof, and conically-hollow plugs 25 26, screw- 5; seated in the outer ends of the couplings. v The plugs 25 26 are formed with vents at the apices of the cavities therein, through which the vapor produced in the generators is discharged. Needles or bars 27 28, flattened 6o slightly on one side, are mounted in the generator-pipes between the coils therein and the plugs 25 26. The needles are of about the same diameter as the interior of the pipes and are used to lessen the capacity of the pipes for the flow of oil and increase the heating or generating capacity thereof by providing a greater thickness or quantity of metal to receive and retain heat. A solid supporting-rod 29 is tapped at its upper end '70 in the lower arm or port of the cross 16 and depends therefrom. The lower end of the rod 29 is tapped into the lateral arm or port of a T 30 and supports the same. The cavity of the T 30 is filled with plaster-of-paris or similar sealing substance 31, and cushiontubes 32 33 are tapped at their inner ends into the longitudinal arms or ports of the T and extend horizontally in opposite directions therefrom. Ts3435aremountedontheouter 8o ends of the cushion-tubes 32 33, and burnerstems 36 37 are mounted in the lateral ports of said Ts and extend upwardly therefrom in alinement with the axes of the coils 21 22. Burner-frames are mounted on the stems 36 37 and are constructed as follows: A collar 38 is mounted removably, replaoeably, and

loosely on the stem, and a base-ring 39 is mounted concentric with the lower end thereof and connected with the collarby angle- 0 irons 40. Supporting-rods 41 42 43 are fixed to and rise from the base-ring 39, and the upper ends of said rods are bent outwardly and downwardly to support a reflector or shade to be mounted thereon. (Not shown.) A top ring 44 is mounted between and supported by the rods 41,42,and 43. A socket 45 is mounted in and extends inwardly from the base-ring 39, and a set-screw 46 traverses the ring and intersects the opening or seat of the socket. A mantle-stem 47 is adjustably seated in the socket 45 and held by the set-screw therein.

A mantle 48, of the Welsbach or similar type, is carried by the loop at the upper end of the stem 47 and depends around the upper end of the collar 38. A chimney 49, of mica, isinglass, or similar material, is mounted within the rings 39 4A and rests upon the angleirons 4:0, inclosing the mantle. Vapor-pipes 5O 51 are tapped at their inner ends in the Ts 3a 35, extend horizontally in opposite directions therefrom beyondthe vertical planes of the plugs 26, are provided with elbows 52 53, whereby they may be turned upwardly, extend vertically to the horizontal planes of said plugs,and terminate in elbows 54 55,0pening to and spaced apart from the vented ends of said plugs. The open ends of the elbows 54 55 are of smaller diameter than the pipes 51 or the burner-stem, as is desirable to provide snilicient air with the vapor in said pipes, and the spaeingapart of the said e1- bows from the plugs is for the purpose of admitting air to said pipes. The cushion-pipes 32 33 are normally full of air at atmospheric pressure and provide cushions for the flowing vapor to equalize the discharge thereof to the mantle through the burner-stems.

The flow of oil and consequent generation of vapor is controlled by the cooks 19 20 and the first gas or vapor is produced in the generators by extraneous heating means, such as an alcohol-lamp, applied to the coils 21 22.

I claim as my invention 1. The gas-fixture comprising a hanger, a reservoir suspended on said hanger, asupplypipe suspended from said reservoir, a cross on said supply-pipe, generators oppositely horizontally extended from said cross, a solid supporting-rod suspended from said cross, a filled T suspended by said rod, cushion-tubes oppositely horizontally extended from said T, burners mounted on the cushion-tubes, and vapor-pipes communicating with the cushiontubes and burners and terminating adjacent to and in alinement with the generators, the

' laterals of said cross and projecting in horizontal planes oppositely therefrom,stop-cocks in the generators, a supporting-rod depending from the cross, a T with a solid center mounted on the lower end of the supportingrod, cushion-pipes tapped into the laterals of the T and extending horizontally therefrom parallel with the generators, Ts on the extremities of the cushion-pipes, burners on the latter said Ts and vapor-pipes communicating with the latter said Ts, extending horizontally therefrom and bent upwardly and inwardly with their terminals adjacent to and in alinement with the terminals of the generators.

4. In a gas-fixture, a suspended supplypipe, lateral generators thereon, vapor-pipes in alinement with and spaced apart from the terminals of the generators, \Velsbach burners on the vapor-pipes and located below and in alinement with the generators and a partition in and between said vapor-pipes, whereby communication between the vaporpipes is out off between the burners.

Signed by me, at Des Moines, Iowa, this 8th day of March, 1898.

CHARLES H. HATFIELD.
